- Imaging
- • Chest x-ray may show masses within the center of the chest (mediastinum or hilum), involvement of the lungs
- or fluid around the heart or lungs.
- • CT scan of the chest, abdomen and pelvis may show enlargement of lymph nodes , spleen or liver or the
- involvement of the lungs or other organs.
- There are also several optional imaging methods, including:
- • Lymphangiogram, which uses a contrast dye injected into the feet to highlight the pelvic and abdominal lymph
- nodes. The dye will stay in the lymph nodes for many months or years, during which the disease can be
- followed by a simple x-ray of the abdomen.
- • A spinal tap or CT or MRI scan of the brain may be done if central nervous system involvement is suspected.
- MRI may allow more accurate assessment of the tumor , particularly in the spinal cord and vertebrae.
- • An imaging scan using the radioactive isotope gallium may show "hot spots" in areas of lymphoma.
-
- Endoscopy and Biopsy
- • Diagnosis is usually made in a lymph node, but a biopsy of other involved tissues (extralymphatic) may be
- performed.
- • Bone marrow biopsy may detect the presence of lymphoma, in which case further studies will be done to
- identify the type.
